| Abstract: | In order to improve the crude oil recovery rate, sodium cottonseed fatty acid alkanolamide sulfate were synthesized from cottonseed oil sludge. The reaction conditions of sulfation were investigated by orthogonal experiments, the results were as follows: n(RCONHCH 2CH 2OH)/n(H 2SO 4)=1∶1.2, reaction temperature 90 ℃ and reaction time 50 min. The obtained alkanolamide sulfate and alkanolamide were used as surfactants in an allkali/surfactant/polymer(ASP) flooding composition which could produce an ultra-low interfacial tension (10 -3 mN/m order) for the crude oil in Karamay Oil Field. |
